Happy World!

Oomura Takeshi is no stranger to bad luck. Three days ago though, his misfortunes seem to be piling up. He gets chased by dogs, sees his house burn down... and dies from a fatal concussion. "Fourteen years of life... my life was too short."

Luckily, Heaven seems to think so too: upon dying, he meets an angel called Elle who immediately resurrects him. Elle explains that Takeshi's father had passed down his role to his son — essentially, Takeshi is now the holder of all the bad luck in the world, and Elle was sent to become his guardian angel.

Of course, Takeshi wants to refuse, so he seizes the opportunity to pass the curse to someone else. However, when it seems his curse is going to affect an innocent little girl, he decides to accept it himself once more. Elle acknowledges his acceptance and then transforms into a human, after which she explains that she has to be near Takeshi 24/7 so she can supply him with good luck. Takeshi isn't particularly happy with this arrangement.
